UNITED STATES JOSEPH F. KAPINOS, OF BUFFALO, NEW YORK.

' OIL BURNER.

Application filed October 29, 1924, Serial No. 746,563. Renewed September 30, 1925.

To all whom it may concern:

Be it known that I, J osnrrr F. Karnvos,

' a citizen of the United States, residing at furnace.

My primary aim is to generally improve upon burners of this class, by providing one which includes a casing having a combustion chamber, wherein walls of the chamber and easing constitute an air passage, through which the air passes, to be initially heated before mixing with the vaporized oil, and being fed into the combustion chamber.

I also contemplate taking the air in, on one side of I the casing, and passing it through the air heating passage, and then directing it downwardly above the passage upon the diametrically opposite side of the casing to enter the combustion chamber, previous to which it encounters'a baflle before mixing with the vaporized oil.

More specifically speaking, I propose to provide a single casting, in the form of a casing, the same being provided at its top with an opening for passage of the flame, and there being a wall extending down wardly and outwardly from this opening and connected with the intermediate portion of the side wall for simultaneously forming a central combustion chamber, and a surrounding air heating passage communicating with said chamber.

Other structural features and advantages derived therefrom will become apparent during the following description and drawing:

In the accompanying drawing, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 represents a central longitudinal section through the improved casting, forming said casing, showing a flame spreader, in elevation, mounted thereon.

Figure 2 is a horizontal section, taken on the plane of the line 2-2 of Figure 1, and looking downwardly.

Figure 3 is a central transverse sectional view, taken on the plane of the line 3-3 of Figure 1. y

Briefly described, the improved burner comprises a lower iron casting, which is formulated into what may be conveniently termed a casing, the casing having an openingin its top, and there being a curved Wall extending downwardly from this opening and connected with the peripheral wall of the casing, to simultaneously form a central combustion chamber and a surrounding air passage. Air entering through said passage is heated from the heat generated in the combustion chamber, and cold air is simultaneously fed into the combustion chamber through a separate pipe. Oil is likewise fed into the combustion chamber, at a point to mix with the incoming heated airpassing downwardly from said passage and encountering a bafiie, acting in conjunction with the oil pipe. A secondcasting is used, the same being supported in spaced relation above the flame discharge opening of said combos tion chamber.

Referring to the drawings in detail, the

reference character 1 designates asubs'tan-- tially discular casing. Asbefore intimated. this casing is provided at its top with a centrally disposed flame discharge opening, and extending downwardly and outwardly from this opening is a wall 2, which joins the peripheral casing wall, as more clearly seen in Figure 3, at a point intermediate the ends. of said casing wall. The provision of this wall 2 simultaneously forms a centrally located combustion chamber 3, and an annular air heating passage l, which surrounds the combustion chamber. Air enters the passage through the intake neck 5, extending laterally from one side of the casing.

iametrically opposite the air intake 5, the casing is enlarged slightly, as indicated at 6, and at this point I provide a vertical partition 7 which extends from top to bottom of the casing, dividing the air passage into two separate passages. The incoming air encounters the partition 7, and is compelled to pass through the elongated opening 8, on opposite sides of the partition.- After passing through these openings, the air is permitted to enter the aforesaid combustion chamber 3. It is to be noted, however, that the. air is prevented from mixing immedi-' ately with the oil and vapor entering the combustion chamber through the pipe 9. fhis result is accomplished by the presence of a batlle plate 10, which extends crosswise oi the lower portion of the partition 7. This battle plate is provided with inwardly V diverging deflector wings 11, extending on in diameter than the flamev discharge open-- ing. The burner is split, with a plurality of supporting legs 14, which rest upon the top wall of the casing. Inpracticaair forced through the intake. 5, through the medium of an appropriate blower. (not shown). Vaporized oil simultaneously enters the combustion chamber through the pipe line. The air passing into the. intake 5 passes around the passages l to the back of the casing, encounters the partition 7, and is forced downwardly through the openings S, on opposite sides of the partition. It then encounters the battles and wings of the latter and enters the combustion chamber to mix with the alreadyvaporized oil. A highly combustible mixture is thus provided, which, when ignited produces an intensely hot flame, escaping through the opening in the top of the casing, and being spread by the conical spreader cooperating with said opening.

I claim:

An oil burner comprising a single casting in the form of a casing, said casing being provided at the center of the top with a flame discharge opening, there being a wall extending downwardly and outwardly from said opening and joining the peripheral wall ofthe casing, simultaneously forming a combustion chamber and a surrounding air heating passage, avertical partition dividing said air. passageinto separate portions, said casing being enlargedadjacent said partition. and termed with openings. for passage of the heated air. into the. combustion chamber, means providingan air inlet for the combustion chamber, diametrically opposite said openings, and a deflector extending laterally across the bottom of said partition, said deflector being provided with inwardly extending. and diverging wings an oil feed pipe leading to said combustion chamber, and a flame spreader cooperative with said flame discharge opening.

In testimony whereof I atlix my signature.

JOSEPH F. KAPINOS.
